That sounds like a challenge.

 

I have water injection ready to install tomorrow or saturday

 

was that enough to feel a power gain or EGT reduction?

 

I have had Snow Performance MPG-MAX kit ready to install for a looong time.

 

Well the common saying is a 10° drop = 1% hp gain.

1% of 320hp is 3.2hp, 20 degree drop equals a 6.4hp gain. The temp drop is more noticeable coming to, then taking off from a stop and the when the mist compensates for less airflow. In those situations the temp can MAT can drop 30°. In those cases I guess you could say its good for a 9.8hp/20tq gain. . This is using water that is around 45°.

 

Another benefit of running cold water in the 33 - 45° range is that you have a secondary or tertiary location to store frosty adult beverages made with barley and hops.

Seriously though, there is a photo that @Tugly took years ago with an endoscope stuck down into the intercooler. The oil accumulation seemed insignificant as Y2KW57 eluded to and specifically stated backed by measurements and scientific methods.

 

nothing noticeable from an EGT standpoint?

 

Back at this and finally wired it "proper" for real world towing use. The pump is still hooked up to the dimmer switch like the pictures before. Now I have split the ground and use a 2 position toggle (two on positions) with a 1/4" activation LED light.

The first ground goes to the body and is for standard misting use. Flip the toggle to this position and the pump turns on at whatever rate the dimmer is set to (0%-100%). The 1/4" LED kicks on as well.

The 2nd ground is more complicated. Ground starts in the engine bay. It leads to a grounding temperature probe in the intake Y. Ground closes at 140°f and opens at 125°f. From there the ground wire goes to a 10psi switch mounted in the intercooler pipe. It then leads to the toggle switch.

Switch the toggle to the 2nd position and now the system is "armed" for towing. In order for it to turn the mister on two things need to happen simultaneously. The MAT must reach 140°f and MAP reaches 10psi. When those two things occur, the LED lights up, pump turns on (at desired %) and misters run until MAT falls to 125°f. If boost falls below 10psi it shuts off. This is so it doesn't run at stoplights, traffic, etc.

Going to give it a good test. If it works I plan on getting a larger tank with an easy fill.

 

Running distilled water or tap?

 

Filtered tap. Didnt run it in close to a year, had to blow out two tips since last use.

 

Did you notice any EGT drop?

 

I will let you know shortly, although my truck doesnt have any EGT issues. Will also get some pictures of how it is set up now.

 

Anymore updates to report?

 

Got the system completely plumbed, wired and functioning. A few things to note, with the S363 the 10psi pressure switch is too light, need to change to a 20psi +/-. It hits 10psi to easy, so once temps hit 140* towing it wants to stay on all the time. Simple fix, just switch out the 10psi switch with a 20psi, the current 10psi is an oil pressure sender for a Generac generator. Think I will keep the 140 degree intake probe though, seems to be a good zone to work with, just adjust the psi switch.

Also thinking about changing the entire pump/tank/nozzle assembly. The washer pump/res worked and cost $0 but doesn't hold enough water to be practical. My thought is to use a 15 gallon FimCo sprayer tank and pump with 1 or 2 larger nozzles that are used for spraying fertilizer/chemicals, more resilient with filters in them. The 15 gallon FimCo sprayer with pump runs $120. Grab a couple nozzles and some hose and leave TSC for under $150. The FimCo will also spray more water in a shorter duration so it theory it will run less and be more efficient.

The other issue is the truck. The turbo/tuning/gearing is dialed in to the point where this is pointless, but it is fun and I enjoy messing with it. With a 15 gallon tank and high flow nozzles it will make for better testing and yield more accurate results. My thought is to mount the 15 gallon FimCo on the transfer tank behind my cab, that way I can see the water level out of my rear view mirror.
